Sponge And Dough
The sponge and dough method is a two-step bread making process: in the first step a ''sponge'' is made and allowed to ferment for a period of time, and in the second step the ''sponge'' is added to the ''final dough's'' ingredients, creating the ''total formula''. In this usage, synonyms for ''sponge'' are ''yeast starter'' or ''yeast pre-ferment''.The phrases "yeast starter" and "yeast pre-ferment" may be considered oxymoronic when the context of "starter" and "pre-ferment" are referring to natural yeast or sourdough leavens which include relatively large populations of lactic acid bacteria. In French baking the ''sponge and dough'' method is known as ''levain-levure''. The method is reminiscent of the sourdough or ''levain'' methods; however, the sponge is made from all fresh ingredients prior to being used in the final dough. Method A sponge ferment is usually a sticky process that uses part of the flour, part or all of the water, and part or all of the yeast of a total- or ...

Bread
Bread is a staple food prepared from a dough of flour (usually wheat) and water, usually by baking. Throughout recorded history and around the world, it has been an important part of many cultures' diet. It is one of the oldest human-made foods, having been of significance since the dawn of agriculture, and plays an essential role in both religious rituals and secular culture. Bread may be leavened by naturally occurring microbes (e.g. sourdough), chemicals (e.g. baking soda), industrially produced yeast, or high-pressure aeration, which creates the gas bubbles that fluff up bread. In many countries, commercial bread often contains additives to improve flavor, texture, color, shelf life, nutrition, and ease of production. History Bread is one of the oldest prepared foods. Evidence from 30,000 years ago in Europe and Australia revealed starch residue on rocks used for pounding plants. It is possible that during this time, starch extract from the roots of plants, such as c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flour Treatment Agent
A dough conditioner, flour treatment agent, improving agent or bread improver is any ingredient or chemical added to bread dough to strengthen its texture or otherwise improve it in some way. Dough conditioners may include enzymes, yeast nutrients, mineral salts, oxidants and reductants, bleaching agents and emulsifiers. They are food additives combined with flour to improve baking functionality. Flour treatment agents are used to increase the speed of dough rising and to improve the strength and workability of the dough. While they are an important component of modern factory baking, some small-scale bakers reject them in favour of longer fermentation periods that produce greater depth of flavour. These agents are often sold as mixtures in a soy flour base, as only small amounts are required. Examples Examples of dough conditioners include ascorbic acid, distilled monoglycerides, citrate ester of monoglycerides, diglycerides, ammonium chloride, enzymes, diacetyl tartaric acid e ...

Leavening Agents
In cooking, a leavening agent () or raising agent, also called a leaven () or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens the mixture. An alternative or supplement to leavening agents is mechanical action by which air is incorporated (i.e. kneading). Leavening agents can be biological or synthetic chemical compounds. The gas produced is often carbon dioxide, or occasionally hydrogen. When a dough or batter is mixed, the starch in the flour and the water in the dough form a matrix (often supported further by proteins like gluten or polysaccharides, such as pentosans or xanthan gum). The starch then gelatinizes and sets, leaving gas bubbles that remain. Biological leavening agents * ''Saccharomyces cerevisiae'' producing carbon dioxide found in: ** baker's yeast ** Beer barm (unpasteurised—live yeast) ** ginger beer ** kefir ** sourdough starter * ''Clostridium perfringens'' ...

Stollen
Stollen ( or ) is a fruit bread of nuts, spices, and dried or candied fruit, coated with powdered sugar or icing sugar and often containing marzipan. It is a traditional German Christmas bread. During the Christmas season the cake-like loaves are called Weihnachtsstollen (after "Weihnachten", the German word for Christmas) or Christstollen (after Christ). Ingredients Stollen is a cake-like fruit bread made with yeast, water and flour, and usually with zest added to the dough. Orangeat (candied orange peel) and candied citrus peel (Zitronat), raisins and almonds, and various spices such as cardamom and cinnamon are added. Other ingredients, such as milk, sugar, butter, salt, rum, eggs, vanilla, other dried fruits and nuts and marzipan, may also be added to the dough. Except for the fruit added, the dough is quite low in sugar. The finished bread is sprinkled with icing sugar. The traditional weight of Stollen is around , but smaller sizes are common. The bread is slathered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Sweet Bread
Portuguese sweet bread ( Portuguese: ''pão doce'' "sweet bread" or ''massa sovada'' "kneaded dough") is a bread made with milk, sugar, eggs, yeast, flour and sometimes lemon peel to produce a subtly sweet lightly textured loaf or rolls. A slightly different recipe is made during Easter that is known as '' folar'' and often contains a hard-boiled egg. The bread was brought to Hawaii by Portuguese immigrants from Madeira and the Azores. Under the name Hawaiian rolls, Portuguese sweet bread is now considered a quintessential dish in Hawaiian cuisine and is widely consumed throughout the United States. Portuguese sweet bread is traditionally made in Madeira and the Azores around Christmas, and the Easter version is made around Easter, but it is also available year-round on the islands. It is uncommon to find this type of bread in mainland Portugal. It is traditionally baked in a stone oven known as a ''forno''. The bread is usually served simply with butter and is sometimes se ...

Brioche
Brioche (, also , , ) is a bread of French origin whose high egg and butter content gives it a rich and tender crumb. Chef Joël Robuchon described it as "light and slightly puffy, more or less fine, according to the proportion of butter and eggs." It has a dark, golden, and flaky crust, frequently accentuated by an egg wash applied after proofing. Brioche is considered a ''Viennoiserie'' because it is made in the same basic way as bread but has the richer aspect of a pastry because of the extra addition of eggs, butter, liquid (milk, water, cream, and, sometimes, brandy) and occasionally sugar. Brioche, along with ''pain au lait'' and ''pain aux raisins''—which are commonly eaten at breakfast or as a snack—form a leavened subgroup of ''Viennoiserie''. Brioche is often cooked with fruit or chocolate chips and served on its own or as the basis of a dessert with many local variations in added ingredients, fillings, or toppings. Forms Brioche has numerous uses in cuisine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gluten
Gluten is a structural protein naturally found in certain cereal grains. Although "gluten" often only refers to wheat proteins, in medical literature it refers to the combination of prolamin and glutelin proteins naturally occurring in all grains that have been proved capable of triggering celiac disease. These include any species of wheat (such as common wheat, durum, spelt, khorasan, emmer and einkorn), barley, rye and some oat cultivars, as well as any cross hybrids of these grains (such as triticale). Gluten makes up 75–85% of the total protein in bread wheat. Glutens, especially Triticeae glutens, have unique viscoelastic and adhesive properties, which give dough its elasticity, helping it rise and keep its shape and often leaving the final product with a chewy texture. These properties, and its relatively low cost, make gluten valuable to both food and non-food industries. Wheat gluten is composed of mainly two types of proteins: the glutenins and the gliadins, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprouting
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth. In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds) to be eaten raw or cooked, which is considered more nutritious. Suitable seeds All viable seeds can be sprouted, but some sprouts, such as kidney beans, should not be eaten raw. Bean sprouts are a common ingredient across the world. They are particularly common in Eastern Asian cuisine. It typically takes one week for them to become fully grown. The sprouted beans are more nutritious than the original beans, and they require much less cooking time. There are two common types of bean sprouts: * Mung bean sprouts, made from greenish-capped mung beans * Soybean sprouts, made from yellow, large-grained soybeans Common sprouts used as food include: * Pulses ...

Malt
Malt is germinated cereal grain that has been dried in a process known as " malting". The grain is made to germinate by soaking in water and is then halted from germinating further by drying with hot air. Malted grain is used to make beer, whisky, malted milk, malt vinegar, confections such as Maltesers and Whoppers, flavored drinks such as Horlicks, Ovaltine, and Milo, and some baked goods, such as malt loaf, bagels, and Rich Tea biscuits. Malted grain that has been ground into a coarse meal is known as "sweet meal". Malting grain develops the enzymes (α-amylase, β-amylase) required for modifying the grains' starches into various types of sugar, including monosaccharide glucose, disaccharide maltose, trisaccharide maltotriose, and higher sugars called maltodextrines. It also develops other enzymes, such as proteases, that break down the proteins in the grain into forms that can be used by yeast. The point at which the malting process is stopped affects the starch-to-enz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amylase
An amylase () is an enzyme that catalyses the hydrolysis of starch (Latin ') into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. Foods that contain large amounts of starch but little sugar, such as rice and potatoes, may acquire a slightly sweet taste as they are chewed because amylase degrades some of their starch into sugar. The pancreas and salivary gland make amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. Specific amylase proteins are designated by different Greek letters. All amylases are glycoside hydrolases and act on α-1,4-glycosidic bonds. Classification α-Amylase The α-amylases () ( CAS 9014-71-5) (alternative names: 1,4-α-D-glucan glucanohydrolase; glycogenase) are calcium metalloenzymes. By acting at random loca ...

Protease
A protease (also called a peptidase, proteinase, or proteolytic enzyme) is an enzyme that catalyzes (increases reaction rate or "speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products. They do this by cleaving the peptide bonds within proteins by hydrolysis, a reaction where water breaks bonds. Proteases are involved in many biological functions, including digestion of ingested proteins, protein catabolism (breakdown of old proteins), and cell signaling. In the absence of functional accelerants, proteolysis would be very slow, taking hundreds of years. Proteases can be found in all forms of life and viruses. They have independently evolved multiple times, and different classes of protease can perform the same reaction by completely different catalytic mechanisms. Hierarchy of proteases Based on catalytic residue Proteases can be classified into seven broad groups: * Serine protease ...
